flac dev - Oct 2013 - in place decoding

Hi Guys,

I'm wondering if it's possible to provide flac with the decoding buffer 
address.

I'm currently  doing a block aligned decoding and I'm copying all data 
given by flac in the write callback to my own buffer but would like to 
skip that step.

If not possible, would you at least consider allocating a memory aligned 
buffer ?
So far the pointer given by the write pointer containing frames are not 
16 or 32 bytes aligned disallowing the usage of aligned SSE loading. At 
least on the Windows platform.

Or

Maybe are the pointers given by the write callback valid until any other 
call ?

Thanks,

So far from my test, I can indeed keep the pointer as it seems valid 
between two decoder write callback.

In that case, it would be great if in stream_decoder.c, you use a 16 
bytes alignment instead of 4 so the buffer given can use SSE aligned 
loading.
